I have been using WiFi without problems other than signal strength. Recently, however, I see that my phone a some point disconnects from my WiFi. So I check and i see that the WiFi spot (my router) is there but it won't connect. I turn WiFi off and on and it connects, but very soon after disconnects and same thing, WiFi spot is there but won't connect. The only solution I have is a restart of my phone. Is there anyone experiencing this issue and have another solution?
